Movable body apparatus, exposure apparatus, and device manufacturing method

A supporting member on which a wafer table is mounted is substantially kinematically supported, via six rod members placed on a slider. Further, coupling members are placed facing in a non-contact manner via a predetermined gap, thin plate-shaped edges provided at both ends in the Y-axis direction of the supporting member. By this arrangement, vibration-damping is performed by the coupling members (squeeze dampers) facing the edges, on vibration of the supporting member mounted on the wafer table. Further, because the supporting member is kinematically supported via the plurality of rod members, it becomes possible to reduce deformation of the wafer table that accompanies deformation of the slider.
